- Voice splitter, referred to as Splitter, is applied to xDSL (xDSL is a collective name for various DSLs, that is, digital subscriber lines, a transmission technology that uses traditional telephone copper wires as the transmission medium.
- Among them, x represents different kinds of DSL technologies, including ADSL ++, HDSL, VDSL, etc.) in broadband communication. The splitter that we often talk about just refers to the ADSL (Asymmetrical Digital Subscriber Line) splitter, which is a voice splitter based on the common line transmission of broadband digital signals on traditional voice telephone lines (that is, ADSL over POTS Splitter). Now ADSL has been Upgrade to newer versions of ADSL ++ and VDSL (Very High Speed Digital Subscriber Line).
- The voice splitter effectively separates the low frequency audio signal (300 ~ 3400Hz) on the line from the high frequency digital modulation signal (20KHz ~ 4.4MHz / 12MHz) of the transmission data, and then sends the audio signal to a PSTN (Public Switched Telephone Network) switch or POTS (Plain Old Telephone Service) phones and fax machines send high-frequency digital modulation signals to DSLAM (DSL Access Multiplexer) / DSL MODEM modems. DSL technology allows users to use multiple telephone extensions, fax machines and ADSL modems without affecting each other, that is, to isolate the current noise generated by POTS telephones from broadband Internet access, to ensure high-quality call results, and to avoid broadband caused by telephone ringing The Internet connection is dropped, which guarantees the broadband Internet download rate and so on at a certain transmission distance.
